Cream butter in a medium mixing bowl; gradually add sugar, beating well. Add egg, beating well.
Sift together flour and cinnamon in a small mixing bowl; add to creamed mixture, stirring well. Gradually stir in milk.
For each wafer, pour 1 tablespoon batter onto a hot, lightly greased griddle, spreading thin with the back of a spoon. Cook until tops appear dry and edges begin to brown slightly. Turn and cook until bottom sides are browned. Remove from griddle, and wrap each wafer around the handle of a wooden spoon. Slide wafers off spoon handle, and cool seam side down on wire racks.
